HayMax™ Pure (approx 5ml) – contains no essential oils. We were asked for a version with no added fragrance or essential oil by many people. So if you’re sensitive, but need to block the pollen, then choose HayMax™ Pure. HayMax is drug-free, non-drowsy, certified organic and 100% natural. HayMax is applied topically with a finger, to the rim of the nostrils and bones of the eyes. It’s not invasive, is incredibly easy to use and can be applied as often as necessary throughout the day.
